How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

About Conduit

About U-Joints (Universal Joints)

U-joints are used to connect two shafts that have a high amount of misalignment.

Metal Garden Hose Fittings

Connect these fittings to rubber or plastic garden hose for a variety of water supply applications.

Zinc fittings have good corrosion resistance. Fittings with a barbed end are also known as hose menders and splicers. Use them to connect lengths of hose or to repair damaged hose. Fittings with a fasten-on barbed end provide a more secure hold than clamp-on fittings and fittings with gripping tabs; slide the hose over the internal barb and tighten the clamp around the hose with the included screws.

Connectors for Thin-Wall (EMT) Steel Conduit

Join pieces of thin-wall (EMT) steel conduit. Compression ends offer a more reliable hold than screw-clamp or push-in ends. Tighten the compression ring to secure. Screw-clamp ends tighten around conduit with screws.

Connectors with O-ring prevent liquid from entering the conduit. They meet UL raintight standards when used with EMT conduit.

Conduit Adapters

Compression × Twist-In Male

Screw-Clamp × Screw-Clamp

Transition between types of metal conduit.

A compression end offers a more reliable hold on conduit than a screw-clamp, twist-in, or threaded end. It pushes onto the conduit; tighten the compression ring to secure. The screw-clamp end tightens around conduit with a screw. The twist-in end attaches to conduit with a few quick turns.

Internally Threaded Ball Joint Linkages

With Seal

Able to stand up to frequent use, these linkages offer excellent wear resistance. They consist of ball joint rod ends with a ball stud attached to simplify mounting. The stud is machined to fit perfectly inside its housing and swivel in all directions—good for clutches, throttles, and shift control rods. Periodic lubrication may be required to keep them operating smoothly.

Linkages with seal have a seal to keep lubricant in and dirt out.

Internally Threaded Inline Ball Joint Linkages

Use these linkages to create inline pivoting connections. The ball-and-socket design allows the ball stud to swivel. All have a liner (also known as a boot) that not only keeps out contaminants, but also acts as a cushion to reduce vibration.

Convert one faucet into two, four, or five convenient outlets. Each outlet has individually operated shutoff valves.

Zinc valves have good corrosion resistance. Some also have a TPR rubber or plastic coating to protect your hands—the coating keeps valves from getting hot in the sun or cold in the winter.

Valves with flexible outlets are easy to install and help keep your hose from kinking.
